Like we can create an image from a Dockerfile, we can create a container from an image too.<\/p>\n
The steps to do that is as follows:<\/p>\n
Deploy a container from an image:<\/p>\n
[root@gw20-lap-doc1 sandbox]# docker run -it centos \/bin\/bash<\/strong><\/em><\/p>\n Now\u00a0create a new folder in the container:<\/p>\n [root@4bab5b1c66ed \/]# mkdir \/My_New_Folder<\/strong><\/em><\/p>\n Check if the folder got created by running a\u00a0ls<\/strong><\/em> command.<\/p>\n [root@4bab5b1c66ed \/]#\u00a0yum install redis -y<\/strong><\/em><\/p>\n This will install\u00a0 httpd service.<\/p>\n Now open another terminal window connecting to your host where the docker is running and run the following command:<\/p>\n [root@gw20-lap-doc1 ~]# docker ps -all<\/strong><\/em><\/p>\n Identify the container ID of the container running in the other terminal window. In my system the one I can find is\u00a04bab5b1c66ed<\/em><\/strong><\/p>\n Now run the following command:<\/p>\n [root@gw20-lap-doc1 ~]# docker commit 4bab5b1c66ed shiju_centos_2<\/strong><\/em><\/p>\n Just create an image<\/p>\n [root@gw20-lap-doc1 ~]# docker commit -c ‘CMD [“redis-server”]’ 4bab5b1c66ed shiju_centos_3<\/strong><\/em><\/p>\n Create an image an execute the command to start redis server in the container that will be deployed using the image.<\/p>\n","protected":false},"excerpt":{"rendered":"
